"We haven't opened the writer's script for Season 4 yet, so it's very hard to be definitive," Gould explained.

"It sure looks that way and I think there would be something a little ingenuous if we have this big build-up and it being a season ender and then we found out that he got out at the last second."

McKean also hinted that Chuck's death may have even been inevitable in the long run, adding: "He felt he was infallible, and he felt if he was questioned or if he was confronted he knew that he knew, or he felt, that he had moral right on his side, and he felt that he could do no wrong. That's a terrible place to be.

"If you can't change who you are essentially, sometimes you'll repaint your house or blow up your car, or you know, these things don't really work, but at least you're doing something. And I think the combination, there's a combination of his inability to get at what was really destroying him caused him to take that last step over the cliff."

So, it certainly looks like he's a goner, especially as McKean also opened up about the time he found out his character was getting the chop...
